The TPS76338DBVT is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. It is designed to provide adjustable supply voltages from 1.2 to 5.5 V with low quiescent current, fast load-transient response, and low-noise performance. The TPS76338DBVT is suitable for use in supplies for processor cores, memory and display circuitry, for consumer electronics and communication applications.

The TPS76338DBVT is a low-dropout linear voltage regulator which uses a band gap reference to accurately regulate output voltage over a wide range of operating conditions. It can provide adjustable VOUT from 1.2 to 5.5 V, with a typical accuracy of ±1.5% over temperature and line. The supply current is typically low, with the device drawing a minimum of 1.9 μA in shutdown mode and a maximum load current of 2 A with a 2.2 Ω internal current-limit resistor. The device includes an internal power-ON reset with a delay of 10 μs and an adjustable undervoltage lockout that can be used to limit the output enable level.

The TPS76338DBVT is a monolithic linear regulator featuring simple circuit design with few components. It is designed to reduce the number of external components required for the power supply, reduce the power dissipation, reduce the cost of the design, and reduce the time required for design verification. It includes an input capacitor for bypassing, an optional output capacitor for low-frequency noise reduction and a load current-sensing resistor. The input and output capacitors are required to ensure stable operation and suppress voltage transients.

The TPS76338DBVT features fast load-transient response with a 300 mV dropout and a 600 mV/μs response rate. The device also features low-noise performance, with a variable low-output noise profile that ranges from less than 2 mVrms up to 4 mVrms over the recommended operating temperature range. It is designed to operate over the extended temperature range of -40°C to +125°C.

The TPS76338DBVT is available in a 10-pin TSOT23-5 package and is suitable for use in mobile phones, notebook PCs, tablets, and other battery-powered applications. It is also well-suited for supplies for processor cores, memory and display circuitry, for consumer electronics and communication applications.
